Fractional differential problems with numerical anti-reflective boundary conditions: a computational/precision analysis and numerical results
Ercília Sousa, Cristina Tablino-Possio, Rolf Krause +1
Twenty years ago the anti-reflective numerical boundary conditions (BCs) were introduced in a context of signal processing and imaging, for increasing the quality of the reconstruc…

Fine spectral estimates with applications to the optimally fast solution of large FDE linear systems
M. Bogoya, S. M. Grudsky, S. Serra-Capizzano +1
In the present note we consider a type of matrices stemming in the context of the numerical approximation of distributed order fractional differential equations (FDEs): from one si…
